During the years I have tested a lot of editors for programming. When running on low-end tech sublime text is a very good option. Atom is to sluggish with a very huge memory footprint. I used to program assembler on the Amiga where every byte was sacred and highly valued. Today’s programmer don’t care much about keeping there program lean, mean and compact. Though, it is very fun to code with VSCode. For simple script coding vi and nano suffice.
